Audio Quality when recording - Xiaomi Mi A2 Lite Questions & Answers

Hi guys sorry if not correct place:
WHat's the audio recording like on this phone? For recording live music for example? I've a redmi 4x and the microphone filter makes trying to use my phone for a whats app band practice impossible with our remote member. It's a known issue on the redmi 4x but not sure if on all Xiaomi phones? Does music sound fairly clear when recorded with ml Redmi A2 lite? Anybody recorded something at a gig? I didn't find any complaints on my googles so hoping it's ok!

It is okay, you can use also the headphone where it has a mono microphone input plug on it...
The frequency response of it is quite nice...
But I am also looking for a converter cable or box, that I can connect to the MicroUSB port and record then Stereo Audio with at least 44 or 48 Khz
sampling frequency... Anyone know of any device or cable that will allow this.
Also I would like to conect something like a professional USB microphone there , like a Blue Yeti USB Mike... Any idea how to do this ?
Do I just need a USB to MicroUSB adaptor or USBtoGo Adaptor ?
Please post any known solutions. Many thanks.
Regards. Stefan.

External Microphone for Video recording.

I searched through the forums and found some posts that said in order to use your external Mic you need a Y adapter. And that it doesn't support stereo, and some other issues.
Can someone link me to a Y adapter that would work along with a good value microphone that I can use during video recording on my Galaxy S III?
I'm surprised that a company hasn't made a product for this yet where you just plug it in and it works. The camera and video quality are great, but the sound is lacking greatly.
You can also get an OTG cable then you can use the yeti and have digital hd stereo

would it work while recording a video?
If I find a mic with a 3.5mm jack can't I just plug it in? the ear buds that come with the phone have a microphone where the volume controls are and it picks up sound during video recording.

the headphone jack can only output a limited amount of power to drive a mic device, any non mobile mic is not going work. if you want high quality sound you must do so with the usb using either an external usb soundcard with analog 3.5mm inputs or just a usb mic like the yeti which is the best you can really get. and yes s3 has native support for almost any kind of usb device so it will work like if you plug in usbdevices to your desktop/laptop as long as it is Plug and play compatible. whether there are good apps for these usage scenarios though is another story.
oh and you are welcome...

Good info, thanks. Looked up the yeti mic you mentioned, but it's kinda pricey at $109 and not exactly portable either. Do you use it?
(EDIT: too bad most jack mics suck)

I was looking for something like this too to go with my SGS3.
Sent from my Transformer Prime TF201 using xda app-developers app
I was looking at these earlier and thought about getting the edutige http://www.amazon.com/gp/product/B004XC6KHS/ref=ox_sc_act_title_2?ie=UTF8&smid=ATVPDKIKX0DER. A few of the reviews mention it working with a couple of android phones. Only issue is it seems to pick up alot of background noise. If anyone decides to get this for their s3 please tell us how it performs.
Not really sure what you want a dedicated microphone for taking videos on a cell phone. If you are looking to make quality videos, you might as well get a decent external microphone and syncing up audio in post production. I know my brother uses this in conjunction with a 60D. Will probably sound a lot better than the $30 options posted above. http://www.amazon.com/Zoom-H1-Portable-Digital-Recorder/dp/B003QKBVYK/ref=pd_cp_MI_0
I want to record videos with decent sound quality at concerts, etc.. I don't want distorted bass and good audio picture. Recommend me ext. microphone for my SGS3, thanks!

SGSIII External Microphone - Suggestions?

So I've gone to several concerts with my Samsung Galaxy S3 and I've noticed... Every single video recording with the stock app is absolutely terribad. The video portion is okay (Great for a smartphone) but the audio is absolutely horrendous. I've lately been wanting to find an external microphone that could possibly connect via the 3.5mm jack and serve as the primary mic for picking up sound.
I've scoured the Interwebs for little success on a good external mic that fit my needs. Here are my findings - correct me if I'm wrong in an area:
1. The mic, in order to be recognized by the SGS3 as a mic, needs to have an impedance of over 1000 omegas and has a TRRS 3.5mm jack.
2. There are actually very few compatible mics that would work with the SGS3. One example is the Edutige ESM 01O, which is overpriced and the specs and reviews do not show that it's a good live music recorder.
3. All other vaguely compatible mics are also not good at recording live music, especially bass heavy music (Which is what I frequent). The compatible lavalier mic I found is not what I need.
4. I actually found a mic that is designed for recording live music - the Edutige EIM-004 - BUT it's not compatible with the SGS3, to my dismay. It also costs $80.
So here's my problem - I need a good external microphone that's compatible with my SGS3 that is capable of recording live music with little distortion. Preferably, I'd like a low cost (Ballpark of $20-$50)I've already got the software covered, there are a few apps that I've looked up that fit my needs.
Here's my phone specs:
AT&T Samsung Galaxy SIII i747 running Cyanogen Mod 10.0.0
I'd really appreciate any help. Posting here is probably the last thing I can try, considering how there's almost nothing out there to help me resolve my situation. Thanks guys.
I really need an answer, guys. Above & Beyond is coming to town in a few days and I'd really like to record them with my SGS3.

I'm also interested. :good:
I'm still looking for a solution myself as I also do concerts recording with my S3. The audio recording sounds much better when you aren't as close up to the speakers. I know it would also help if we could block some of the sound coming in. Like ear plugs to block some of the dB.

I've heard of a few apps that reduced the mic's gain and applied a few filters to clean up the sound, but I don't know how much the sound quality improves.
http://www.parts-express.com/pe/showdetl.cfm?partnumber=390-810
Here's a calibration mic might work.
I like this mic, David. The only problem is the impedance. The mic is 200 ohms but the SGS3 needs a mic of at least 1000 ohms in order for the mic to be recognized as a mic. Otherwise it'll only be recognized as a headset.
For concert recording try the negative mic gain in Boeffla kernel.
I9300XXEMD3, Boeffla 2.12, Earsonics SM3v2
i know this isnt going to help much, but i simply cover the mic's slightly with my hands. when i have my phone in the air recording something, phone horizontal, i place my hands in front of the mic holes, so it only records sound from behind my hands. this helps ALOT.
and what do you know...i'm also an A&B fan. recorded last weekend with the above trick:

Nice! Hope you had a good time at the show haha. I think this is going to be my temporary fix to the problem (Considering how A&B is coming to town tomorrow I've lost all hope of finding a mic in time), but I'll still need a solution for when I go to Ultra... Because their Funktion One systems are definitely too powerful for this fix.

A quick answer for yah Mecronmancer.
- otg usb cable (couple of bucks)
- Digital to Analogue converter with USB (Appr $30) Behringer UCA222 is what I have.
- USB recording app...USB Audio Record or Audio Evolution. Both apps from Same guys.
- Microphone or analogue stereo inputs (Sky is the limit here)
- a rom that supports this arrangement. My i747m S3 with Stock ICS 4.0.4 works flawlessly with this arrangement.
You will get 16bit, 44.1k Stereo recording quality. Will it record while another app is recording Video? That I don't know. Thiis may be your one caveat. I might give it a shot sometime this week and report back.
UPDATE:
I simultaneously recorded USB Audio with the USB audio app and Video+mic audio with the built in ICS video app successfully. So if it was me, I would combine the 2 source recordings using a PC app and have HQ audio with Video. You just need to time align the 2 in sync very easily since you would have lofi mic audio and hifi usb audio sources.

What is the power source for the ADC?
Can anyone comment on the audio quality recording stereo to a phone with this setup?

@guy48065
The UCA222 can be powered from your Smart Phone, in my case, the SGS3. I had to buy a female-A-USB-to-Male-micro USB plug. They are inexpensive. I can't remember if this cable had to be an OTA version. (On The Go)
In my car, if my memory serves me well, I had the USB split with one end going to the SGS3 and the other into my USB cigarette lighter charger. I didn't end up using it in my car because it didn't interact well with the phone call audio stream etc. Lots of glitching.
RE-Recording Sound Quality
Unless your a professional audiophile or sound engineer with impeccable trained ears, the recording quality is flawless and blows away what I could do without it. An app like Audio Evolution Mobile is a great combo, especially if you have a larger and fast tablet.
Ok so it doesn't get power from the phone and it has no batteries. Darn. ..I was hoping it could be a handy mobile recorder.
A splitter usb + battery supply is borderline too cumbersome.
Price is great though -- I might tinker with it as a means to dub vinyl to files.
Does anyone make a $30 adc that includes a phono preamp? Lol.

You miss read.
YES...it CAN definitely be powered from the smartphone.
Read my reply post again.
I didn't think phones were capable if supplying usb power so when you wrote about the OTG cable *and* the splitter with power I assumed you needed both.

No problem. It's a very small investment for what it can offer.

Which ROM has the best audio quality from the 3.5mm headphone jack?

I have been trying a lot of custom ROMs recently on my Z2 Plus and I noticed the audio quality from the 3.5mm headphone jack is not particularly good on any of them. When listening to a piece of music or a podcast with quiet sections, a crackling noise is audible that makes it hard to hear any detail in the audio. The problem is most notable at low volume levels of just a few notches. I tried disabling any audio enhancements like the 'AudioFX' app that comes with Lineage-based ROMs, but this did not make much difference.
I listened to the same MP3 files on my ZTE Axon 7 and the audio is crystal-clear with no crackling present in the slightest. I'm using a pair of Audio Technica ATH-M50 monitor headphones.
I know the ZTE Axon 7 has a Hi-Fi audio DAC which might explain why it sounds so much clearer, but I didn't expect the difference to be this much... Is the bad audio quality just a limitation of the ZUK Z2's hardware, or is it something that the custom ROMs are not implementing correctly?
Which ROMs have the clearest audio quality from the headphone jack?

Flash this mod and use neutron/ poweramp with 24 bit hifi audio enabled.
There is a noticable difference in audio quality

Thanks, I actually tried both of these tips before making this thread but I wasn't overwhelmed by the difference in audio quality... When playing music I still hear the crackling/static kind of noise during the quiet parts. I think it's probably a limitation of the hardware more than anything else.
Do you guys think using a 3.5mm to Type-C adapter with a built-in DAC would solve this problem? Then I could play music through the Type-C port instead of using the headphone jack.

You can always use a external dac via usb c port. Someone from zukfans.eu said it is working. But external dacs are expensive. Type c to 3.5mm jack adapters wont do anything if it does not have any dac inbuilt

Okay, thanks. The reason I mentioned the Type-C adapters is because I thought some of them were marketed as having an inbuilt DAC. But that could be wrong and the ZUK might not have compatibly to use it anyway.
Yeah, I don't like the thought of buying an external DAC since I don't intend on keeping this phone much longer anyway. I'm just having trouble choosing my next handset since the smartphone market is so stagnant at the moment. LG V30 would be good for audio quality but it uses PWM which hurts my eyes too much.
try paranoid rom nougat version, it was the only rom in which I felt the audio quality was better. ZUK 2 clearly have poor hardware, my old moto g3 sounds much better.

Audio jack low volume

Hi guys, anyone might have an idea how to bypass the stupid EU limitation on the audio jack volume?
Last time that I've done it it was so easy!
On a Pocophone you need to change the region outside EU and the audio DAC is enabled, louder and clearer audio.
I really need this as I have some professional studio headphones and his phone has the weakest volume of everything I've tested with, other phones, laptop, tablet.
No need to tell me to change the headphones or buy an headphone amp please.
Many thanks!

Redmi Note 8 Microphone Problem

Anyone face the same problem?
I have a Boya BY-A100 External omni condenser microphone. I want to create an amateur home recording. for my bass trombone. The built-in microphone is too noisy and sensitive for me since I can hear "windy" sound when recording in my room, since there is no fan and silent enough. And there is vehicle sound which just passed in front of my house that can be heard clearly in my recording (rather than my trombone).
When I plug the external microphone, It's blinking in notification. And my recording has no sound at all. When I use the recorder app, my sound is just "skipping". It's annoying. I have another lavalier external microphone, but it has the same problem.. But the weird is when I plug my earphone (XIaomi in-ear HD) everything is working fine.
I have found the same problem in YouTube that the use of splitter may work. Then I bought a cheap U-shape splitter with the earphone and the external microphone plugged, then i plug it to my phone. But still, THERE IS NO SOUND AT ALL. It's annoying so much.
My Begonia (Indonesia) is Global MIUI 11 with Android 10 QGGMIXM.
having same problem mate
the same problem with the Boya By - MM1 external microphone
I have the same problem with the Boya By - MM1 external microphone. I read that the problem concerns all external microphones connected to the minijack socket on the Redmi Note 8 Pro phone. When a microphone is connected, the headphone diode flashes and the recorded sound is interrupted at the same frequency. I have reported a problem to Xiaomi technical support many times. I have been ignored. People around the world report a problem with microphone malfunction. This is a common problem. If anyone wants to use an external microphone, the Redmi Note 8 Pro is useless.
Is the problem due to a bug in the android system software or is it a technical defect?
Fix Found!!!!!
The trick is fairly simple.
I have a Boya MM1 mic and it was very very annoying that the mic icon kept blinking in note 8 pro.
Fix is simple.
1. Get a y split cable ... 3.5 mm male to two 3.5 mm female converter.
2. Connection 1 - input The cable with spirals (for DSLRs) to the smartphone to the mic end of the splitter.
3. Dummy connection- Input the smartphone end of the other cord into the other split cable end.
This fix works like magic, for more info
Type external mic not working in XIAOME now 8 pro in YouTube edwin bonus guy.
The video is Japanese but you'll get the gist.
Thank you
Man that was a pain but i luckily found a solution with some cables and adaptors i had at home:
I previously used IRIG pre to connect my condenser mic to my phone via 3.5 mm jack, so what i did from there is connect it to a cheap "ugreen" chinese mini soundcard/splitter (to the headphone/mic combo jack), i connected this to a USB to USB-C adaptor which i then connected to this stupid phone and TA DAM! it worked!
